SPECIFICATION forming part of Lettere Patent No. 605,586, dated June 14, 189e.

Application led November 18,1896. Serial No. 612,593. (No model.)

' To all whom it may concern:

' With these various objects ih viewmy invention consists, essentially, ofa supporting-frame provided with shoes or runners, whereby the device can be quickly and'easil y transported from place to place, and a de' pending supporting-rod having a lever centrally pivoted to its lower end, said lever passing through a box which slides upon the supporting-rod and has a series of pins passing therethrough and directly above the operatang-lever, said box or block being adapted to be moved upward step by step upon' the supporting-rod by means of the lever, and said box or block being connected-to the stump to be pulled or extracted. Y My invention consists also in certain details of construction and novel-ties of combination, all of which will be fully described hereinafter and pointed out inthe claim.

In the drawings forming a part of this specification, Figure 1 isa view showing the invention in use. Fig. 2 is avertical sectional view. Fig. 3 is a diagrammatic view showing the manner of using thc stump-extractor in a horizontal position.y Fig. 4. is a detail view` showing the connection between the supporting-rod and operating-lever.

In.r carrying out my invention I employ a main framewhich consists of four inclined standards A,which meet at a common point, and upon their upper ends is placed a cap B,

through which passes the supporting-rod'C,`

said rod being secured by means of anut D.

Shoes or runners E are placed upon the bottom of the standards, as most clearly shown, by means of'vvhich the frame can be dragged about as desired and placed over the stump to be pulled.

.The supporting-rod C is preferably jointed,

:as shown at C', in order to permit a certain amount of lateral play without throwing any undue strain upon the main frame.

' Vorking up and down upon the 'supporting-rod is va box or block F, which I term the powerbox, said box being preferably constructed of two stout plates of metal' united at their 6o 'upper/end, the upper end being perforated,-

as shown at F', tovperinit the introduction of the supporting-.rod C. The sides of the box havea series of perforations G made therein, said perforations being arranged in parallel rows, asV most clearly shown in the drawings. The operating-lever II passes between the side plates of the box, said lever being centrallypivoted to thelower end of the supvporting-rod, said rod being bifurcated at its 7o lower end, and the operating-lever is provided with bearing-'plates H' at the center, which plates are notched, as shown at H2, said vnotches being adapted to receive the liftingpins I, which pins are passed through perforations Gf in the sides of the" box above the operating-lever, and by pulling down upon one end of the lever the opposite end is raised, whichV raised end engages the lifting-pin I and raises the power-box'along the support- 8o ing-rod. Another pin is then inserted above the lower end of the lever, and the elevated fend 'of the lever is then depressed, which causes the lower end to rise, lifting the liftbox still more along the supportingrod. The 8 5 lower 'end of the power-box is therefore con-` nected to the stump, and in practice I prefer to arrange an eye K at the lower end of the said box, and to which is connected a chain L, said chain passing through a pulley-block 9o M and connected at itsrupper end to a crosspiece N, attached to the side standards of the frame, said pulley-block M having a chain lO extending therefrom, which is placed around the stump to be pulled. rIfhus it will vbe seen that the power is doubled by the use of the pulley-block M, the cross-piece'N, and' chain L. Eyebolts P are attached to the shoes or runners E, and connected to the said eyebolts are theropfes. R, which pass upward through lthe roo pulleysR', carriedl upon the ends of the operating-lever, whereby horse or man power can be employed, as desired.

Now in operation the machine is drawn in place directly over the stump to be pulled. The power-box is then lowered and the chains and lever adjusted. The lever is then worked up and down, and by changing the position of the pins I the power-box will be moved upward along the supporting-rod C, and as it is so moved the stump will of course be drawn upward.

The construction and arrangement of the various parts are such that the device can be handled in a quick and easy manner and with an expenditure of a minimum amount of power.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v In a stump-extractor, the combination of the standards having runners at their lower ends, their upper ends being brought together at a common center, of the cap-plate arranged upon the top of said standards, a short rod screw-threaded at its upper end and passing through said plate, a nut for holding said rod and adjusting it in said cap-plate, a supporting-rod loosely connected to the opposite end of said short rod, an operating-lever pivotally attached at its center to the lower end of the supporting-rod, the bearing-plates at the 1nid dle of said lever having notches arranged at each side of the supporting-rod, the powerbox through which the supporting-rod extends, said box being freely movable vertically upon said rod and having a series of pcrforations arranged in longitudinal parallel rows, the removable lift-pins fitting in said perforations, the pulley-block M, the crosspicee N, chain L connected to the lower end of the power-box, passing around the block and having its opposite end attached to crosspiece N, and the chain O connecting the block with the stump, substantially as shown and described.
